I'm 5' 10'' 175lb with fairly low BF %.
Current lifts:
Squat: 3x5x290
Press: 3x5x155
Bench: 3x5x220
Dead lift: 1x5x355
When I did starting strength for about 6 months I didn't eat enough to gain good amount of weight. Around 3000cal a day with about 120gram in protein. My weight went up from 165 to 175 with no visible increase in fat. Now I wanna add a gallon of milk to my current diet but I'm not sure how to reset/change my current training. The lift numbers I mentioned above are all what I have stalled at so they are pretty damn hard and at the edge of major form break down. I doubt I can just add a gallon of milk and expect those numbers to go up the next day or two. Also I do get about 8.5 hours of sleep every night.
How do you think I should resume my training with this diet change?
